The compatibility of a 16-inch MacBook Pro with a 15-inch MacBook bag is a common concern among Apple laptop users. The dimensions of these portables, while seemingly close, can make a significant difference when it comes to fitting into an Apple laptop bag designed for slightly smaller laptops.

The 16-inch MacBook Pro, with its larger screen and overall dimensions, may struggle to fit comfortably into a MacBook Pro bag or a leather MacBook bag designed for a 15-inch laptop. The additional size can result in a tighter fit, making it challenging to slide the laptop in and out smoothly.

With the 2025 MacBook Pro M4's even slimmer profile (e.g., 0.44 inches thick), fit concerns are amplified. The M4's dimensions can cause it to "rattle around" in older 15-inch bags, risking scratches or instability.

For M4 users, opt for flexible cut-and-sew bags, which accommodate slight size variations better than rigid designs. Always measure your Mac versus the space you want to place it in your older bag. 

In 2025, prioritize bags with expandable compartments to future-proof for M4 and beyond, ensuring a safe carry experience without compromising protection.

For other sizes, the risk of potential damage can increase when forcing a larger laptop, say a 14-inch Apple laptop into a MacBook Pro 13-inch bag or one not specifically designed for its dimensions.

Best Bag for the Job

It's essential to consider that MacBook shoulder bags are usually crafted with specific measurements in mind to ensure a secure and comfortable fit. In this case, if you have a 14-inch Apple laptop, select a MacBook Pro 14 bag for the best fit.

While some bags may have a degree of flexibility, attempting to use a MacBook Pro 15-inch bag for a 16-inch Apple laptop might compromise the protection and ease of use that the bag is intended to provide.

Moreover, the design of MacBook shoulder bags often includes additional padding and compartments tailored to the laptop's size. Attempting to fit a larger laptop into a bag designed for a slightly smaller one might result in a lack of proper cushioning and protection for the device.

Can a 15.6-inch Laptop Bag Fit 16-inch Laptop?

Whether a 15.6-inch laptop bag can fit a 16-inch laptop depends on several factors, including bag design and the amount of interior padding. Measure the exterior dimensions of the 16-inch laptop and check them against the internal dimensions of the bag's laptop compartment to find out.

While most 15.6-inch bags are designed to accommodate laptops slightly larger than their size, some might have tighter dimensions. Thicker padding around the laptop compartment can significantly reduce available space. Consider bags with minimal padding if you're unsure about the fit.

While the nominal size is 16 inches, the actual dimensions of the laptop might vary slightly depending on the manufacturer. Thinner bezels on newer laptops allow for a larger display in a smaller footprint.

A 16-inch laptop with thin bezels might be more likely to fit a 15.6-inch bag than one with thicker bezels. Let's look at an example.

MacBook Bag Fit

Let's consider the specific example of a laptop bag for MacBook Pro 15-inch and a 16-inch MacBook Pro. The internal dimensions of a typical 15-inch MacBook Pro bag are roughly 14.3 inches wide and 10 inches deep.

The 16-inch MacBook Pro measures 14.01 inches wide and 9.77 inches deep. Based on these dimensions, the 16-inch Pro will technically fit inside a laptop bag for MacBook Pro 15-inch.

However, the fit might be snug, leaving minimal space for additional accessories. Additionally, thicker padding within the Mac Pro bag could further restrict space and make it difficult to insert or remove the laptop.

MacBook Bag Purchasing Advice

Before purchasing any bag, measure your laptop's exact dimensions, including its width, depth, and thickness. Carefully compare the internal dimensions of the bag to your laptop's dimensions, ensuring sufficient space for a comfortable fit.

Even better, call the company and talk to a real person about your concerns. Have them check the measurements and address the fit issues you have. Spending a little time now to make sure your laptop will be compatible it's much easier than taking delivery and having to return a bag that doesn't fit.

While it's possible for a 15.6-inch laptop bag to fit a 16-inch laptop, it depends heavily on specific designs and dimensions.

Testimonial

"I have three MacCase products- 2 of which are the Flight Jacket models (shown above). My 10 year old 13" Flight Jacket is going strong, and even doubles as a protector for my iPad Air when needed."

"The leather is supple and as strong as the day I purchased it. My newest Flight Jacket is a 2025 MacBook Pro 16" model with a few improvements, such as an added pocket for an AirTag, but still built to the specifications that first led me into buying my first Flight Jacket. "

"I find all three to be the absolute most durable and finely crafted products that I've ever bought. They will outlast the electronics. What's amazing is how as they age they develop their own unique and beautiful "patina". And all I do is once a year rub the leather down with some beeswax to keep the leather supple and water resistant. An excellent investment"
